As performance issues evolve with the technologies, so must our approach to evaluation. In System Performance Evaluation, top academic and industrial experts review the major issues now faced in this arena. In a series of structured, focused chapters, they present the state of the art in performance methodologies and applications. They address developments in analytical modeling and its interaction with detailed analysis of measurement data. They also discuss performance evaluation methodologies for large-scale software systems, in general and in the context of critical applications, such as nuclear reactor control and air transportation systems.
